Okay, so I read all the responses, and just want to say that each child is different, and there is a BIG difference in potty training girls, and potty training boys. First off, I am a stay at home mom, and so my input is from someone who spends alot of time with thei children. I understand that alot of mothers work and that makes it more difficult than what I had. Second, the man that I LOVE to read is called T. Berry Brazelton. He has a little teeny book called Potty Training the Brazelton way. That's what really helped me. He lays it out step by step, week by week. My daughter had NO interest in potty training until the was about 3 years old. Now, we had EVERYONE telling us to potty train her, and at times I felt like an unfit mother because I wouldn't until I felt she was ready. So, shortly after she turned 3, she did it. And I guarantee you that she was potty trained in two days. We did it over a weekend. She has never had an accident, never had to wear diapers to bed, and has REALLY high self-esteem, as far as never hiding, holding it in, or any issues with potties. Now that's just my experience. But my point is, to try and wait as long as you can until they are ready, cause when you wait, it makes it much easier, it's not really like training as it is them willing to learn. I did the sticker chart as well and it worked great. I wouldn't advise the cookie or reward snack method. Secondly, sometimes when you're out and you know you want them to go potty and they don't need to, but you know that you won't be stopping anytime soon, one little trick that worked was letting them play with their hands in the water cause the feeling of the water makes them want to go potty. Good Luck!
